IMPROVEMENT IN HOSE-COUPLINGS.

Specification forming part-of Lett ars Patent No. 176.24l, dated April 18, 1876 application filed I January 29, 1876. I

To all whom it may concern Be it known that I, GEORGE W. PRICE, of

the city and county of'San Francisco, Oalii'ornia, have invented" a new and Improved of which the following is a specification: 1

The invention consists of a tapered ring outside .of the hose, and screwing" intoone of the parts oflit h coupling over another tapercd ring inside of the hose, so as to bind the-hose and thus attach it to the coupling and it also consists of a kind of] detachable hinge-joint at one'side of'the 'coupling,zn id sliding keys and hooks at the otheriside', for

Y fasteningthe two parts of the coupling, all as hereinafter described.

-Figure 1- is partly a sideelevation, and

I partly a longitudinal section of my improved coupling, and Fig. 2is an end ele\-'ation.

Similar letters of referenceindicate corresponding parts; I a

' A'is the inside tapercd ring, and B the outside tapering ring, between which the'hose 0 is attached to the coupling D by screwing side, andG represents permanent hooks on the opposite side of the coupling, by which the latter are fastened with keys .H, the keys be ing fitted on the couplings by aslotted-flange, I, and a screw, J, so as to be connected, for keeping them in position for use, and at the same time allowing them to-slide freely.

One of the couplings has a spring, K, of elastic material, fitted in the end to be comprcssed against the face of the flange of the other coupling, to pack the joint tightly.

, Having thus described my invention, 1 claim as new and desire to secure by Letters Pat ent- 1. In hose-couplings, the circular wedge B, screwed in hold! r ow r the hose, and holding its end against a shoulder of the ring A, as shown and described, for the purpose specified.

2. The detachable hook E, permanent hooks G, and the keys H, combinedwith the hosecoupling, substantially as specified.

3. The combination of packing K with couplings D, hooks E G, and keys H, substantially as specified.

GEORGE PRICE.
